Modern laryngeal framework surgery (LFS) requires an exact understanding of the laryngeal biomechanics and precise pre-operative planning, for which bi-planar imaging is not sufficient. The aim of the study was to test whether MIMICS, a commercially available software package for three-dimensional (3D) rendering of high-resolution computerised tomography (HRCT), is suitable for 3D imaging of the larynx, analysis of laryngeal biomechanics and pre-operative planning. We examined four cadaver larynx and one patient larynx. In the five larynges, all relevant structures and landmarks could be 3D visualised. Superimposing of two HRCT scans shows that when the arytenoids move from 'respiration' to 'phonation', they perform a rotating, translating and tilting motion. Moreover, we could demonstrate that the vocal fold elongates by 7% with cricothyroid approximation. We conclude that MIMCS is well suited for 3D imaging of the larynx, analysis of laryngeal biomechanics and pre-operative planning of LFS procedures.
现代喉框架手术（LFS）需要对喉生物力学有精确的理解和精确的术前规划，而双平面成像则不够。本研究旨在测试 MIMICS 是否适合喉的 3D 成像、喉生物力学分析和术前规划，MIMICS 是一种商用的高分辨率计算机断层扫描（HRCT）三维渲染软件包。我们检查了四个尸体喉和一个患者喉。在这五个喉中，所有相关结构和标志都可以进行 3D 可视化。叠加两个 HRCT 扫描显示，当杓状软骨从“呼吸”移动到“发音”时，它们会进行旋转、平移和倾斜运动。此外，我们还可以证明，当环状软骨甲状软骨接近时，声带会延长 7%。我们得出结论，MIMICS 非常适合喉的 3D 成像、喉生物力学分析和 LFS 手术的术前规划。
